@mcp-b/smart-dom-reader is a DOM extraction library for agent workflows. It turns a live document into structured data, interactive element maps, and stable selectors while keeping token usage low.

​
When to use this package

  • You are building DOM-aware tools for agents or browser automation.
  • You need structured page summaries or ranked selectors.
  • You want DOM extraction without bringing in a full MCP runtime.

​
When not to use this package

  • You only need to expose browser-page tools. Use the runtime packages instead.
